Compilation film of the British Army during the Battle of Amiens and the Advance to the Hindenburg Line, Western Front, August 1918.

Near Bapaume a German “anti-tank gun’ lies in an unidentifiable wreck with its crew dead beside it. Shells burst in the distance. Two 6-inch Mk VII guns are drawn by Holt tractors to new positions, probably near Sapignies, passed by a general service wagon of the New Zealand Division. British soldiers clear debris and trees in a thin wood near Bailleul. Near Thiepval (?) a dead German lies over a Maxim machinegun on a sledge. Three British soldiers carrying German Maxims and 08/15 Bergmanns walk past him. ‘There is only one good boche - and that is a dead boche.” At a dressing station a prostrate German officer is given water by an RAMC corpsman. “The quality of mercy is not strained.” Just outside Abbeville a large group of Germans, captured in the advance, waits to move.

Pieces of History

German Prisoners of War

Jonathan F. VanceProfessor and Canada Research Chair in Conflict and Culture, Department of History, University of Western Ontario

The emotions of capture are etched in the faces of new prisoners of war. There is fear – my life is now in the hands of an enemy who may or may not let me live. There is the kind of bewilderment that exists only in the mind of someone just emerging from the fog of war. There is relief – at last, I’m out of the shooting war. There is guilt – should I have done more to prevent being captured? On top of it all, there is exhaustion.

The emotion of fear probably came first since the moment of capture was the most dangerous time for a prisoner. It was a reality of the First World War that the protection given to prisoners under the 1907 Hague Convention was not always observed in the front lines. Throwing aside one’s rifle and yelling “Kamarad” was no guarantee that the plea for mercy would be heeded, particularly if the approaching soldier had seen his unit decimated by enemy fire. By the same token, a platoon that was weakened by casualties and struggling to hold a hard-won position sometimes could not spare a couple of infantrymen to escort prisoners to the rear areas. In such cases, soldiers implicitly understood that the safest option for their unit was to shoot the prisoners and keep it to themselves.

And then there were the rumours that circulated through both sides of no man’s land about a particular battalion that never took prisoners, or about captives who were killed rather than being sent to the safety of a prison camp. A soldier who had been fired up by such stories might well wave aside his enemy’s pleas and pull the trigger instead. The faces you see in these films, then, represent the lucky ones, the soldiers who actually survived to become prisoners.

We should also be aware that there did exist a degree of sympathy between soldiers. Atrocities were committed on both sides, but often the sight of a cowering enemy soldier elicited a feeling of pity in the attacking soldier. This is not the demonic Hun depicted by the propagandists, he might think; this is a man like me, with a family, perhaps a wife and children. We are both caught in a war that is not our doing; I will treat him as I hope he would treat me, with kindness and consideration.

The exhausted Canadian sharing coffee and hardtack with a captured German became a stock propaganda image, as a way to demonstrate the kindness of our Canadian boys overseas. But just because they were propagandized does not mean such situations did not take place. On the contrary, many a soldier would share with his prisoner a water bottle, a packet of rations or a cigarette, because the fact that he was a fellow soldier was now more important than the fact that he was an enemy. There is genuine good humour in the image of the captor clowning with the captive by putting on his cap and pulling a face.

Once the new prisoner made it through the moment of capture and reached relative safety, his experiences in captivity became more typical. The First World War was a very labour-intensive conflict. It was the first truly mechanized war, but much of the heavy work was still done the old-fashioned way – by tens of thousands of men digging, carrying, lifting and moving. Neither side had any scruples about using prisoners as forced labour in or directly behind the front lines. We know that German units used their POWs to dig trenches, move ammunition and carry supplies – all tasks forbidden under international law – and Canadians may well have done the same. But such scenes would never have made it onto film. Instead, a much more common image is of German soldiers acting as stretcher bearers, bringing the wounded, Canadian and German alike, to safety. For the captors, this had the advantage of freeing up infantrymen who had been temporarily co-opted as stretcher bearers – every German prisoner who could carry a stretcher meant that one Canadian could go back to the firing line. But it also had value for the prisoners themselves. Many contemporary accounts tell of new prisoners who were almost pathetically keen to prove themselves useful by helping with the wounded. Carrying a stretcher, after all, was much better than being shot.

Prisoners were also a valuable source of information. They were searched for maps, papers or anything else that could have intelligence value (or even monetary value – Canadian soldiers were known as tireless souvenir hunters, and quickly stripped any item that could be sold to non-combatant troops in the rear areas. Rifles, canteens and other military equipment were confiscated and sent to salvage dumps. Then, German-speaking officers questioned the men about their unit and the defences on their side of the line. Probably, few POWs were as helpful as some of those who were filmed (including the one who is evidently hard of hearing, likely from artillery bombardment), but the evidence suggests that prisoners were actually forthcoming with information about what was going on in their own trenches.

Finally, the symbolic significance of prisoners should not be underestimated. It was important to depict German prisoners on film because they were very visible signs of success on the battlefield. In the bloodbaths of 1916 and 1917, when success was measured in yards of pulverized earth, scenes of a few bedraggled German soldiers proved that something concrete had been achieved. The Battle of the Somme, for example, was a notorious example of horrific casualties sustained for very little territorial gain, but footage of prisoners being marched away from the battlefield in this clip at least proved that there were a few enemy infantrymen who would never again fire on Canadian soldiers.

In the open campaigns that began in the summer of 1918, prisoners became even more dramatic evidence of success. Now, it was possible to show to Canadians images of long lines of Germans soldiers captured in battle as the Canadian Expeditionary Force swept across northern France. Scenes of POWs being marched away from the battle for Bourlon Wood in 1918, often combined with pictures of rows of captured artillery pieces, confirmed to people at home that the tide had finally turned. The Allies had the Germans on the run, and such images seemed to prove that they were just as happy to surrender as fight.

Statistics on German POWs captured by Canadian troops are far from complete. We know that over 4000 were captured at Vimy Ridge in April 1917; over 5000 on August 8, 1918, the first day of the Battle of Amiens; and roughly 6000 in the three-day battle for the Drocourt-Quéant line in September 1918. But these are only three of dozens of engagements fought by the Canadian divisions, and the total number of prisoners taken may never be known. In any case, the cold statistics tell us less about the experience of captivity than these moving images. The men we see remain nameless, but their faces speak volumes about the impact of war on the individual.

Military Logistics of the Canadian Expeditionary Force, 1914–1919

Michel LitalienHistorian

Front-line soldiers cannot fight effectively unless they are fed, clothed and equipped properly and have sufficient ammunition and gear to face the enemy. And they cannot hold their lines for long if they are not supported by solid military logistics.

Canadian military logistics is a dimension of the history of the Canadian Expeditionary Force (CEF) that is often overlooked. Yet just a few days after Canada’s entry into the First World War, it was obvious that there was no way of ignoring it. When huge numbers of military and civilian volunteers showed up at Valcartier, near Quebec City, in August 1914, logistical support services, which had only recently been established, were soon put to the test. Clothing and equipping the members of the first contingent turned out to be a real headache. Manufacturers had to be found and contracts drawn up in a hurry for the production of uniforms, boots, belts, weapons, vehicles and so on. From a logistical standpoint, mobilizing the first contingent destined for Europe was a nightmare.

Throughout the Great War, the Canadian Expeditionary Force’s logistical support system was an immense, complex operation. Of all the support services, the Canadian Army Service Corps (CASC) was the most diversified. Its main responsibilities were transporting combat troops, delivering equipment and materials, and providing the troops with fresh supplies. In addition to these essential tasks, the CASC also evacuated the wounded (ambulance drivers belonged to the corps), salvaged equipment that had been captured from the enemy or left behind on the battlefield and delivered mail. The CASC worked closely with the Canadian Ordnance Corps, the Canadian Army Medical Corps, and the Canadian Artillery Corps for the transportation of specialized ordnance.

The CASC operated from seaports located hundreds of kilometres from the battlefield, all the way to just behind the front lines. Its replenishment system could supply not only small groups of just a few men but also formations the size of an infantry battalion (approximately 1,000 men).

Resupplying front-line units was a multistep process. From ports and depots, supplies were first taken by railway to railheads. From there, CASC units were responsible for moving the supplies by truck or light railway to supply dumps. These operations took place in the third line of supply. Thanks to their small size, light railways could run and reach areas closer to the front lines more easily. It was also harder for enemy artillery to pinpoint them. The administrative area behind the front lines was crisscrossed by light rail lines that were built and maintained by Canadian railway troops.

From the supply dumps, the CASC’s divisional train and ammunition supply column, both of which were horse-drawn, were responsible for bringing supplies closer to the front lines, to their respective divisions or individual units. This was the second line of supply.

Lastly, operations to supply front-line units constituted the first line of supply. These units had to come back to the rear to get their own supplies of gear, ammunition, weapons, technical and communications equipment, water, medication and food. These supply expeditions were carried out chiefly at night so that the soldiers could not be seen by the enemy. But assigning combat troops to this task meant that a battalion’s defensive positions at the front would be short of manpower for a time and so vulnerable to enemy attack.

Toward the end of the war, however, a Canadian officer from Montreal proposed using the tumpline system — the method that Canada’s aboriginal people and coureurs de bois had used to carry large loads on foot. Before the introduction of this system, infantryman had to carry supplies in their arms, thus limiting the quantity of materials due to their size and weight. The tumpline system, which involved the use of a head strap, allowed the soldiers to carry more weight and freed up their arms, thus giving them more freedom of movement. With this system, each soldier was able to transport a greater quantity of supplies and so fewer men were required for the job, leaving more troops to ensure the defence of the front lines.

Besides regularly providing drivers and vehicles to other units, the CASC also maintained and repaired its vehicles. It also had to make sure that the troops were fed, which meant that fresh and hard rations had to be allocated and distributed properly; its military cooks oversaw the operation of field bakeries and butcheries.

The CASC was not the only logistical support corps to play a key role in the CEF. The Canadian Ordnance Corps was responsible for procuring, storing and distributing uniforms, boots, equipment, weapons, ammunition and shells to combat troops. Specialized supply depots, located in the second line of supply, helped ensure more effective distribution.

The Canadian Ordnance Corps’ other major role was to maintain equipment in the field. The repairmen in the specialized ordnance mobile workshops could get closer to the deployed units and repair their weapons, both light and heavy, as well as their equipment. If the mobile workshops were not able to do the repairs on site, the weapons and equipment were shipped to heavy or stationary workshops at the rear, where virtually anything could be reassembled or rebuilt. The small detachments of the Ordnance Corps worked closely with the various units of the Army Service Corps.

Despite the gradual mechanization of the war, horses remained a vital component of the CEF. The cavalry, the artillery and, of course, the Army Service Corps used huge numbers of horses right up to the end of the war. At one point, Canadians were using as many as 24,000 horses and mules in their overseas operations. Horses could often manage in places where motorized vehicles could make no headway! Inevitably, some horses suffered injuries or fell ill. The Canadian Veterinary Corps operated mobile sections to take care of horses; it also ran veterinary hospitals for horses, advanced remount depots and specialized basic provisions depots.

Other logistical support services also played a crucial role in enabling combat troops to get on with their job. The Canadian Postal Corps, for instance, helped maintain the morale of soldiers at the front, at the rear and also those convalescing in hospitals. Army chaplains, who constituted the smallest organized support group, provided religious services to Canadian soldiers of different faiths and offered moral support at difficult times. Lastly, despite the enemy’s efforts to maintain a naval blockade by submarines, the Canadian Forestry Corps ensured that Great Britain, France and the Canadian Expeditionary Force obtained all the timber they needed to carry out their military operations.

Thousands of men served in these various organizations. The Army Service Corps, for example, counted over 17,000 officers and non-commissioned soldiers in its organization. Even if these units were not combat troops, many of them, including the Army Service Corps, played important roles in all military actions. One hundred and four members of the CASC were killed, and 363 were wounded.

Engineers on the Western Front

Bill RawlingHistorian, Department of National Defence

The conflict that raged in different parts of the world from 1914 to 1918 was a total war: entire populations and economies were mobilized, and millions of people were killed on the battlefield or died of disease and famine. It has also been called an industrialized war, where the management techniques of large manufacturers were applied to the task of killing one’s enemies. Engineers, therefore, played a prominent role and in such a wide variety of enterprises that simply providing a list would take several pages, so only those that employed large numbers of troops will be described here.

Forestry

The Western Front made huge demands in matériel, lumber being an excellent example. Wood was needed to revet trenches, support the roofs of dugouts, for plank or corduroy roads, and as sleepers for tramways and railways. These tasks became the responsibility of the military engineers, specialized forestry units being formed for the purpose. Lumberjacks, graders and other skilled men from within the lumber industry were recruited. They cut timber and ran their own sawmills to provide a finished product.

The first forestry companies in the war were formed in 1915, in France. More units were created in England to harvest the island’s local resources. All of these were gathered into a corps in 1916 that eventually comprised 43 companies, and was of such a scale as to require its own hospital system. The men received more than the normal food rations, considering the fact that they were engaged in continuous hard labour.

Their work, in Britain and France, saved huge amounts in shipping costs, not to mention freeing up lumber supplies for such industrial endeavours as shoring up mines and building trawlers and other vessels. Nor did the forestry corps limit its work to cutting and preparing wood. Many of its units supported the Royal Air Force by clearing, draining, levelling and grading sites for aerodromes. By the time of the Armistice 11,750 men worked within its ranks, with another 6000 attached in various capacities.

Railways

Closer to the fighting there was a need for heavy-capacity means of transport to get the prodigious amounts of ammunition, food, water and other necessary matériel to the front line. One solution to such an intimidating logistical problem was the construction of tramways with specialized labour, with other specialists maintaining and operating the tractors and rolling stock. The result was a system of transport similar to that of a large North American city run by the Canadian Railway Troops. The troops worked on the Western Front and also in Palestine, the 1st Bridging Company serving there in the last part of the war. The system was, in fact, a merging of two networks, tramways closer to the front operating with gasoline-powered tractors while light railways a little farther behind used steam power, the whole being linked to France’s broad gauge system, which had been built in the decades before the conflict.

In the end, the war became too mobile for railway troops to keep up, and when an Armistice was declared on November 11, 1918, the railways were some 30 kilometres behind the forward troops, in spite of the work of 25,000 railway construction engineers, two-thirds of them Canadian. Still, they had served their purpose in the almost four years of near-static warfare that characterized the Western Front from late 1914 to the summer of 1918.

Tunnelling

It became clear in the early months of the First World War that operations above ground were distinctly hazardous, even suicidal, hence the trenches and dugouts in which soldiers took shelter. An obvious course was to begin operating underground, and within the Canadian Corps three specialized tunnelling companies were formed. Recruited in the main among miners and clay-kickers (the latter dug smaller tunnels to run gas and water mains under city streets), they began their work in 1915, and their role was multi-faceted. First, they used the galleries they excavated under enemy lines to listen in on his own work, the aim being to give fair warning if he began to threaten Canadian lines underground. Second, they might pack the galleries with explosives to destroy enemy defences; generally, however, such operations proved disappointing as German forces usually occupied the crater thus created before Canadian or British troops could reach it.

Tunnelling was particularly hazardous. Working underground can release toxic gas capable of disabling or killing, or one could find oneself tunnelling into an enemy gallery, leading to vicious little skirmishes fought with knives and digging tools. When fighting shifted from a mutual siege to more open warfare in 1918, tunnellers applied their skills to other work, disarming booby traps in dugouts and other underground facilities as the Allies advanced towards the German border. In fact, the only Canadian military engineer ever to be awarded the Victoria Cross was Captain C.N. Mitchell, a tunneller who in 1918 removed explosives from a bridge while under attack.

Field Engineering

The most versatile of the engineers operated on the front line. Originally organized in field companies of a hundred men or so, in 1918 they were reorganized into larger battalions and even brigades. Regardless of how they were administered, their tasks were widely varied. Just behind the front line they were responsible for building and maintaining roads, as well as providing water for humans and animals, the latter task requiring some of them at least to possess knowledge of how to locate and test the precious liquid. To give just two examples, part of the preparations for the assault on Vimy Ridge included laying over 40 miles (65 km) of four-inch (10 cm) pipe, with five pumping stations and a total storage capacity of 560,000 gallons. Following the successful advance at Amiens in August 1918, one of the deepest penetrations achieved on the Western Front, the Canadian Corps and its allies found itself in the midst of a plain scorched dry by the summer sun, but engineers needed only two days to locate sufficient water to keep forward troops satiated.

In the front lines proper, sappers, as they were called, dug trenches, or oversaw this work done by the infantry work parties, and prepared defensive positions with the copious use of barbed wire. On occasion, as for a trench raid, for example, they were called upon to destroy such wire, using long cylinders filled with explosive called ammonal tubes or bangalore torpedoes. When that front line advanced, as in 1918, bridging became a most crucial sapper task, as forward movement could not be maintained without ammunition, water, food, and the other necessities of making war, all of which needed to be transported forward on roads or railways, both of which needed bridges to get across rivers and other, similar obstacles. Small structures made of cork sufficed to get the infantry across, while prefabricated materials called Inglis bridges carried heavier loads.

At the time of the Armistice what could be called field engineers (as opposed to railway and forestry troops) could count 14,285 men within their ranks, with responsibilities only somewhat less diverse than their numbers.

Unending Seige : Amiens

A Canadian Deception

The scene was now set for toppling the German militarism that in various forms had kept Europe trembling for more than 50 years. Over the long, painful weeks the Allies lived through in the spring of 1918, the Canadians had learned much. They had also had time to rebuild their strength after the successful but costly attacks of 1917.

The sector now reserved for them was that around Amiens. To give the Canadians the advantage of surprise, they were taken 60 kilometres north of the city. Accustomed to having the Australians opposite Amiens, the Germans also knew the Canadians, whom they had seen spearheading British assaults. Two battalions and two first-aid stations were set up in front of Kemmel, where constant traffic of assorted messages was set in motion and picked up by the Germans. Between 30 July and 4 August, in deepest secrecy, the rest of the Canadian Corps descended to the south. Their discretion was facilitated by the gloomy weather, which reduced German air sorties, and the fact that only the division commanders knew the assault target. This secrecy caused numerous logistical problems - for example, the artillery would have almost no time to prepare. Opposite Amiens, the Canadian officers studying the terrain fooled the Germans by wearing the trademark soft hat of the Australian soldiery.

The noise of preparations for the largest mechanized battle ever seen up to that time revealed nothing to the enemy. In spite of all the precautions, however, some German units were wondering about the movements they had detected. Some 604 tanks of all kinds and thousands of horses would give the battle an aspect that was both ancient and modern.

The Black Day of the German Army

Just before dawn on 8 August the attack opened with the firing of 2,000 guns. In addition to the tanks, the soldiers could rely on two motorized machine-gun brigades, a battalion of cyclists to serve the Corps and a section of heavy mortars mounted on trucks. A thousand French and 800 British planes took to the air. During this brilliant assault, which would seriously undermine the morale of the German troops, the Canadians advanced 13 kilometres at the head of an immense front more than 30 kilometres wide. Australians, British and French were also in the attack, their role being to keep clear of the advance of the Canadians, who had more ground to cover to reach their objectives. The Canadians lost 1,036 men killed, 2,803 injured and 29 taken prisoner, losses that were largely offset by their remarkable advance, the most impressive on the western front since 1914. The Germans had to accept 27,000 casualties, including 16,000 taken prisoner - 5,033 of them taken by the Canadians, who also seized 161 artillery pieces and a large number of machine guns and anti-tank guns. Though the Allies were left with only 132 tanks to start with the next day, the Germans had lost seven divisions. The confidence of their High Command was shaken by the realization that its war machine was no longer effective.

An interesting experiment that day involved the use of 30 Mark V tanks to transport the troops of the 4th Division to the opposing trenches. However, many men were bothered by the heat and by the exhaust fumes that entered the passenger compartment. A few fainted; others got out and walked. The drawbacks associated with the Mark Vs could not be rectified and these tanks were not used again during that war.

Canadian Corps Advances

During the night of 8/9 August, the British High Command decided to lend its 32nd Division to the Canadians, who wanted to withdraw their 3rd Division from the front. The Canadians of the 3rd Division had already marched about 10 kilometres to the rear when they were recalled, as the British had changed their minds. The men were exhausted on their return. It was therefore decided to use only one of their brigades at the front, which required the 1st and 2nd divisions to expand the sectors they were covering. Under these conditions the attack of 9 August could not get under way until around 11 am, without the element of surprise of the day before. At a cost of 2,574 casualties, the Canadians took 6.5 kilometres of ground.

The pressure continued to mount for several days, but the momentum of 8 and 9 August was indeed lost. The number of available tanks fell to the point where, on the 12th, there were only six left. Despite their 11,725 casualties from 8 to 20 August, the Canadians had sounded the beginning of the end of the German army by advancing nearly 30 kilometres and securing the ground thus taken. In the whole operation, the Germans recorded 75,000 casualties.

A month earlier the French had seized the initiative from the Germans. In this context, the battle of Amiens would have a decisive impact. It shattered the last hopes of the German High Command, along with any confidence they might have had that their troops still wanted to fight. The success of the Canadian troops was based partly on surprise, the concentration of their strength and co-ordination among the various arms (planes, tanks, guns, machine guns).

After Amiens

Although by August 13 1918 the Allied offensive had been definitely checked, the German leaders could no longer doubt that the initiative had passed from their hands. On that date, at a conference held at Spa with Field-Marshal von Hindenburg, Reichschancellor Count von Hertling and the Foreign Secretary, Admiral von Hintze, in attendance, Ludendorff, while opposing any voluntary surrender of ground, admitted "that it was no longer possible to force the enemy to sue for peace by an offensive". Since the defensive alone could hardly achieve that object, the war would have to be ended by diplomatic means. Hindenburg, on the other hand, derived some comfort from the fact that "the enemy had once more failed to extract all possible advantages from his great initial successes" and that German armies were "still standing deep in the enemy's country." Next day, at a Crown Council presided over by the Kaiser, His Majesty ordered peace negotiations to be opened through the King of Spain or the Queen of the Netherlands.187 It was also about this time that orders were issued calling off large-scale air attacks planned against the British and French capitals by German bombers using thousands of one-kilogram incendiary bombs. While it was proclaimed to the world that these cities were being spared on humanitarian grounds, there seems little doubt that the inevitability of a German defeat was the main reason for the cancellation of the attacks. Throughout the war British and French planes dropped some 14,000 bombs on German soil. A British plan to attack Berlin, however, failed to materialize owing to insufficient aircraft capable of such a mission.

In the meantime Allied plans on the Western Front were undergoing revision. As early as the evening of August 11, as German resistance stiffened, Marshal Foch had shown himself willing to modify objectives and consider alternatives to further offensive operations on the Amiens front. At that time large-scale operations were due to be resumed on the 15th. But on the 13th General Debeney asked for and received a day's postponement of the assault by his army; and next morning General Rawlinson was given the same extra time in which to complete his preparations. Sir Douglas Haig has revealed in his diary that he shared Rawlinson's misgivings about attacking the well-prepared Roye-Chaulnes defences and that he was resolved that the French First and British Fourth Armies should merely "keep up pressure on that front" in order to hold the enemy's attention, while he prepared to strike elsewhere with the British First and Third
Armies.

There is no doubt that Rawlinson was considerably influenced by representations made to him by General Currie, upon whose forces the burden of a major share of a renewed offensive must fall. At a meeting on the morning of August 14 the Army Commander showed Haig a letter (accompanied by air photographs taken the previous day of the German positions) in which Currie set forth the arguments against renewing an operation which would "cost a great many casualties" without obtaining adequate results. He suggested that if the attack were found to be absolutely necessary it should be postponed in order to allow time to "recover the element of surprise." He recommended that an alternative, and better, course would be to withdraw the Canadian Corps from the line, and after resting it for a few days employ it on the Arras front in a surprise attack in the direction of Bapaume. An advance in this sector coupled with an attack by the French from their present line, might well force the enemy to abandon his positions west of the Somme without the necessity of a frontal assault.

This last suggestion was in keeping with Haig's own ideas. An exchange of letters with Foch on the 14th brought no agreement about postponing operations at the Somme, and that evening a telegram from the Generalissimo asked Haig "once more to maintain the date already set." The Field Marshal, however, had made up his mind to limit the Somme attack to a series of set stages, and on the afternoon of the 15th he pressed his arguments at Foch's advanced headquarters at Sarcus (twenty miles south-west of Amiens). "I spoke to Foch quite straightly", his diary records, "and let him know that I was responsible to my Government and fellow citizens for the handling of the British forces." Foch's resistance had already been weakened when he learned from General Debeney that morning that the projected attack on Roye "would certainly be difficult", and even if mounted would leave the French forces too weak to maintain it. "I definitely came around to the opinion of Field-Marshal Sir Douglas Haig", he wrote in his Memoirs, and he agreed that the Amiens offensive should not be pressed.

A new operation order issued by British G.H.Q. directed the Third Army, which was holding a nineteen-mile front north of Albert, without delay to "press the enemy back energetically in the direction of Bapaume"; the Fourth Army while continuing its preparations for an attack would be prepared to follow up any German withdrawal towards the Somme. Farther north the First Army would take advantage of any German retirement to exert pressure south-eastward from the Arras sector; under favourable conditions, it would attack Monchy-le-Preux and Orange Hill.

In a letter confirming his acceptance of Haig's proposals Marshal Foch made it clear that he was depending on the British operations to be developed with sufficient impetus to ensure a resumption of the thrust south of the Somme. He went on to thank Sir Douglas for his cooperation, which had completely freed the Amiens area and the Paris-Amiens railway. For an offensive north of the Aisne he was now going to transfer the French First Army from Haig's command back to Pétain's group of armies. Accordingly the Franco-British boundary was shifted northward to the Amiens-Chaulnes railway, and the relief of the Canadian Corps by French troops began on 19 August.

On the night of August 19-20 the 2nd Canadian Division began moving northward by bus and train to rejoin the First Army in the Arras sector, followed the next night by the 3rd Division. A number of days were to elapse before the 1st and 4th Divisions made the move. General Currie closed his Headquarters at Dury on the 22nd. During the day he called on a number of senior commanders and had the satisfaction of being told by General Byng that the Canadian performance at Amiens was "the finest operation of the war".
